It's official: Kid Rock will play Detroit's Ford Field on Jan. 15, celebrating his 40th birthday (which is on Jan. 17) and opening his tour in support of his new album, "Born Free."

Ford Field will be rechristened 40 Field in honor of the occasion, and several guests are expected to join Rock for the bash. Country star Jamey Johnson will open the show.

Tickets for the show go on sale Nov. 26 at the box office, Ticketmaster locations and at www.livenation.com. Prices will be announced shortly.

Rock had announced the Ford Field show during his annual Halloween Party on Oct. 30 in his Clarkston rehearsal facility; a planned monster truck show had to be rescheduled before the concert could be announced. He also said that a Comedy Central roast would follow the concert on Jan. 17 at the Fox Theatre, but no details have been announced.

Rock and his Twisted Brown Trucker Band are also rumored to be performing at halftime of the Detroit Lions annual Thanksgiving Day game at Ford Field, but that has not been formally announced, either.

Rock's initial "Born Free" tour includes 27 dates during January, February and March, including shows in Saginaw (Jan. 21), Grand Rapids (Jan. 25) and Toledo (Jan. 26). The album, Rock's follow-up to 2007's triple-platinum "Rock N Roll Jesus," came out Tuesday (Nov. 16); Rock will perform at the "American Music Awards" on Nov. 21 on ABC, while MTV, VH1 and CMT are airing a "Kid Rock: Born Free" documentary and Fuse TV is showing "On the Record: Kid Rock."
